Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a prone support device. Background Technology

[0002] The prone position refers to a posture where the body is face down with the chest and abdomen against the bed (or a supporting surface). It is commonly used in medical treatment, rehabilitation, and daily rest. In medical settings, prone ventilation is suitable for patients with acute respiratory distress syndrome and severe hypoxemia (such as severe pneumonia). Gravity helps open the alveoli in the back, improving ventilation, reducing pressure on the lungs from the heart, and increasing blood oxygen levels. This position requires medical personnel to operate, avoiding pressure on the face and chest, and protecting the eyes, mouth, nose, and joints. Prone support devices are used to support the prone position, primarily to distribute pressure, maintain unobstructed breathing, and prevent nerve or blood vessel compression. These devices must be regularly cleaned and disinfected to prevent cross-infection.

[0003] Chinese patent publication number CN219250760U discloses a prone position protective device, including a protective body and an outer sleeve. The outer sleeve is sleeved onto the surface of the protective body. The protective body consists of an outer covering layer and a filling layer, with the outer covering layer covering the surface of the filling layer. The protective body comprises a headrest pad, a chest and abdomen pad, a knee pad, and an ankle pad, which are distributed sequentially along the direction of the human body structure. The headrest pad... The surface is provided with a forehead, cheek, and chin from top to bottom. The lower surface of the cheek has a channel opening.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0034] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-8 A prone support device includes a main support 1, a head support device 2, a middle side support device 3, a leg support device 4, and a posture adjustment device 5.

[0035] The attitude adjustment device 5 includes: a fixed column 51, a flip plate 52, a support frame 53, a servo cylinder 54, and a hinge frame 55. The fixed column 51 is hinged to the top left side of the main support 1. The left side of the flip plate 52 is hinged to the end of the fixed column 51 away from the main support 1. The two support frames 53 are respectively fixedly installed on the front and rear sides of the bottom middle of the main support 1. The bottom of the two servo cylinders 54 is respectively hinged to the front and rear sides of the top of the support frame 53. The two hinge frames 55 are respectively fixedly installed on the right side of the two flip plates 52. The output ends of the two servo cylinders 54 are respectively hinged to the two hinge frames 55. The attitude adjustment device 5 also includes two auxiliary support mechanisms, which are respectively installed on the front and rear sides of the left side of the main support 1.

[0036] When in use, when the patient lies prone on the main support 1, the head support device 2 supports the patient's head, the middle side support device 3 supports the patient's chest and abdomen, the leg support device 4 supports the patient's legs, and the posture adjustment device 5 is used to adjust the patient's limb posture to avoid muscle soreness caused by the patient maintaining a prone position for ventilation, which can cause lumbar muscle stiffness in patients with underlying lumbar diseases, making it impossible for the patient to maintain a prone position for ventilation for a long time.

[0037] The extension of the output ends of the two servo cylinders 54 of the attitude adjustment device 5 causes the right side of the flip plate 52 to move upward, and the shortening of the output ends of the two servo cylinders 54 causes the right side of the flip plate 52 to move downward. The extension of the output end of the front servo cylinder 54 and the shortening of the output end of the rear servo cylinder 54 cause the flip plate 52 to rotate backward. The extension of the output end of the rear servo cylinder 54 and the shortening of the output end of the front servo cylinder 54 cause the flip plate 52 to rotate forward. Multi-angle rotation of the flip plate 52 is beneficial for multi-angle adjustment of the flip plate 52.

[0038] In some embodiments, the auxiliary support mechanism includes a support plate 56, a fixed frame 57, a sliding rod 58, and a spring 59.

The two support plates 511 are respectively fixedly installed on the front and rear sides of the bottom left side of the flip plate 52. The support plates 511 and the guide wheels 510 correspond one to one. The outer wall of the guide wheel 510 is in close contact with the bottom of the support plate 511.

[0040] When the flip plate 52 is adjusted at multiple angles in this utility model, the bottom of the flip plate 52 contacts the guide wheel 510, causing the guide wheel 510 to move. The movement of the guide wheel 510 causes the inner end of the sliding rod 58 to slide within the fixed frame 57, causing the spring 59 to undergo elastic deformation. The guide wheel 510 provides elastic support for the flip plate 52, which is beneficial for providing elastic support for the flip plate 52.

[0041] Example 2: In some embodiments, such as Figures 1-8 As a preferred embodiment of the present invention, the head support device 2 includes: a fixing plate 21, a first hook and loop fastener 22, a first hook and loop fastener 23, and a height-increasing plate 24. The fixing plate 21 is fixedly installed on the top right side of the main bracket 1. Multiple first hook and loop fasteners 22 are fixedly installed on the top surface of the fixing plate 21. Two first hook and loop fasteners 23 are fastened to the first hook and loop fasteners 22. The height-increasing plate 24 is fixedly installed on the top of the two first hook and loop fasteners 23.

[0042] Preferably, the head support device 2 further includes a face support frame 25, which is fixedly installed on the top of the two heightening plates 24.

[0043] In this invention, the patient's head is placed on the face support frame 25, and the heightening plate 24 is used to elevate the face support frame 25 so that the patient can breathe normally. The front-to-back and left-to-right positions of the heightening plate 24 and the face support frame 25 can be quickly adjusted by the first Velcro female buckle 22 and the first Velcro female buckle 23 to adapt to different patients and facilitate the adaptation to different patients' head positions.

[0044] In some embodiments, the middle side support device 3 includes a pad 31 and a heightening strip 32. The pad 31 is fixedly installed on the left side of the fixing plate 21. The pad 31 has a plurality of ventilation holes 33. The plurality of heightening strips 32 are fixedly installed at equal intervals between two adjacent ventilation holes 33 of the pad 31.

[0045] In this invention, the pad 31 is used to support the patient's chest and abdomen, and the heightening strip 32 is used to elevate the patient, which helps the ventilation holes 33 to breathe.

[0046] Example 3: In some embodiments, such as Figures 1-8 As a preferred embodiment of the present invention, the middle side support device 3 further includes an air hole adjustment mechanism. The air hole adjustment mechanism is installed in the pad 31. The air hole adjustment mechanism includes: support rods 34, a moving frame 35 and a blocking strip 36.

Multiple fans 38 are fixedly installed on the left side of the pad 31, and the protective net 39 is fixedly installed on the air inlet of the fan 38.

[0048] In this invention, rotating the threaded rod 37 causes the movable frame 35 to move back and forth, which in turn causes multiple blocking strips 36 to move back and forth. The multiple blocking strips 36 block the ventilation holes 33, and the ventilation effect is adjusted by the blocking range of the ventilation holes 33. The fan 38 introduces external air into the pad 31 and discharges it through the ventilation holes 33 to dissipate heat from the patient's chest and abdomen, preventing some older patients from overheating and causing discomfort when lying prone.
